There seems to be something totally fishy with the way margin display
properties work:
(test-overlays
(insert "ABC")
(let ((o1 (make-overlay 2 3)))
(overlay-put o1 'display '((margin left-margin) "Z")))
(set-window-margins (get-buffer-window (current-buffer)) 8))
this causes Z to appear in the margin and causes B not to appear
in the body of the text.
That seems like a bug to me. It seems to me that a property that puts
something in the margin should not alter the appearance of the text
it is on.
Does anyone think the current behavior is desirable?
